This invention relates to an improved dasher for use in connection with a butter churn or the like, and in carrying the invention into practice it has been my primary aim to generally improve 5 upon structures of this class by providing one which is, structurally speaking, distinguishable and characterized by certain improved elements and a coordination thereof such as is calculated to provide a structure which will more aptly serve the intended purposes.

One feature is predicated upon the use of a simple supporting lid applicable to a receptacle, said lid being provided with attaching clamps and a special fixture and driving means for an inner and outer shaft assembly for operating the dasher blades.

The principal novelty, however, is predicated upon the double or duplex shaft assembly, the supporting bracket therefor, and a simple, positive driving means, the arrangement being such that the inner or dasher shaft is vertically adjustable to regulate the position of the dasher blades in relation to the bottom of the churn or other commodity receptacle.

Indicated along more explicit lines, the particular purpose and novelty, by way ofcontrast with similar prior art structures, relates to the provision of an arrangement of inner and outer shafts forming a unique shafting assembly wherein the inner shaft is slidable through the outer shaft and maintained in adjustable position by a simple set screw and collar arrangement, this shaft assembly being intimately coordinated with a simple U-shaped bracket provided with well balanced and properly arranged bearing and guiding means and serving as suitable accommodation means for the intermeshing gearing actuated by a simple hand-crank.

Other features and advantages will become more readily apparent from the following description and drawings.

In the drawings:

Figure 1 is a view in section and elevation showing a churn provided with a lid and dasher arrangement constructed in accordance with the principles of the present invention.

Figure 2 is an elevational view at right angles observing Figure 1 in a direction from left to 50 right.

Figure 3 is a top plan view of the arrangement depicted in Figure 1.

Figure 4 is an enlarged detail sectional and elevational view illustrating the principal fea- 55 tures in the assembly.

Figure 5 isa view showingthe simple clamping means. Referring to the drawings in detail the receptacle or churn proper is denoted by the numeral 6 and. this is of appropriate type. It is adapted 5 to accommodate a disk lid 1 having a marginal retaining rim 8. At diametrically opposite points are L-shaped brackets 9 carrying retaining screws It provided with clamping blocks ii to engage the receptacle and hold the lid firmly in place. 10

Mounted on the central portion of the lid and rigidly attached thereto is a substantially U- shaped adapter or mounting bracket I2 whose lower arm l3 as shown in Figure 4 is provided with a socket forming a bearing M for the lower 15 end of a tubular perpendicular rotary shaft Hi. The upper arm l6 has a similar bearing I! through and beyond which the upper end of the shaft I5 extends. The shaft i5 is rotated through the instrumentality of a bevel pinion l8 driven by 20 a larger gear I9 which is turned by a hand crank 20 mounted in a bearing 2! carried by the upright portion of the bracket. The inner or solid shaft is denoted by the numeral 22 and is of appropriate length and is fitted in the tubular shaft 25 I5 and is vertically adjustable through said shaft and through a central opening in the lid. It is provided at its upper end with an adjusting and retaining collar 2.3 held in place by a set screw 24, The lower end portion, which depends into 30 the receptacle, is provided with a cross head 25 having simple paddle blades 26 and 2'! connected thereto. It will be observed that the blades are disposed in reverse angular position so that they are more or less intersecting in end elevation as 35 illustrated in Figure 2. It'is believed that this simple double paddle arrangement provides a unique agitator or stirrer. The solid shaft 22 is bodily liftable so as to adjust the height of the paddle blades. This is a feature of refinement, 40 that is the use of an adjustable solid shaft 22 mounted in a gear driven outer or tubular shaft l5 which shaft is in turn mounted in the bracket l2, the said collar 23 being carried on the upper end of the shaft l5 so as to provide for the requi- 45 site vertical adjustment of the dasher per se.

I am aware of the fact that the prior art to which the invention relates embodies many different types and kinds of dasher construction. So far as I have been able to ascertain by in-- vestigation and observation, I believe that I have perfected here a unique arrangement which is characterized by the simple clamp retained lid provided with the fixture or bracket l2 to accommodate the special gearing and shaft assembly. The essential novelty, however, as before indicated is in the specific construction of the bracket l2 and the coordinated shafts 22 and I5 which provide a steady rotary movement and at the same time permits the paddle blades to be raised and lowered to the most suitable elevation in the main receptacle or churn 6 to accomplish the best results depending on the consistency of the product being churned.

It is though that persons skilled in the art to which the invention relates will be able to obtain a clear understanding of the invention after considering the description in connection with the drawings. Therefore, a more lengthy description is regarded as unnecessary.

Minor changes in shape, size, and rearrangement of details coming within the field of invention claimed may be resorted to in actual practice, if desired.

Having thus described the invention, what is claimed as new is:

In an assemblage of the class described, a lid, a substantially U-shaped bracket arranged vertically on said lid, the lower arm of said bracket being secured to the lid and formed with a socket constituting a bearing, the upper arm being formed with an aperture and depending ring aligned with said socket and forming an upper bearing, the intermediate portion of the upright part of the bracket being formed with a bearing, a crank mounted in said last named bearing, a gear on the inner end of said crank, a tubular shaft having its lower end mounted in said socket and its upper end extending through and beyond the aperture in the upper arm of the bracket, a set screw equipped collar associated with the upper end of said tubular shaft, a pinion on the intermediate portion of the tubular shaft in mesh with said gear, a solid shaft slidably mounted in said tubular shaft and slidable through the collar and, adapted to be held in variable adjustable positions through the instrumentality of the collar and set screw, and dasher blades secured to the lower end of said solid shaft.
